Description

Technical Field

[0001] This utility model relates to the field of ENT drug delivery technology, and in particular to a machining tool for a ZM-25 right-angle valve. Background Technology

[0002] The ZM-25 right-angle valve is a mass-produced cast aluminum part. Both the front and side end faces need to be precision machined. The machining accuracy is high and the demand is large. Therefore, tooling is needed for quick clamping and positioning to reduce equipment downtime and simplify the machining process to meet the needs of the production line.

[0003] The existing grippers have a slow clamping speed, are time-consuming and labor-intensive to operate, lack a foolproof anti-misalignment device, and are prone to clamping misalignment, which can lead to out-of-tolerance machining dimensions or even scrap. Furthermore, the front and side sides need to be machined in steps, which increases the time for changing clamps, resulting in low machining efficiency, which is far from meeting the needs of the production line.

[0004] Therefore, it is essential to invent a machining fixture for the ZM-25 right-angle valve. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a ZM-25 right-angle valve machining fixture. This fixture solves the problems of existing grippers having slow clamping speed, time-consuming and labor-intensive operation, lack of error-proofing devices, and a tendency to misalign the clamping, leading to dimensional errors or even scrap. Furthermore, the need for separate machining of the front and side surfaces increases replacement time, resulting in low machining efficiency that falls far short of production line requirements. The ZM-25 right-angle valve machining fixture includes a first hydraulic gripper, a second hydraulic gripper, a drive support structure, a first stop, a height-limiting screw, and a right-angle valve. The drive support structure is fixedly installed on the outer sides of both the first and second hydraulic grippers. The first stop is fixedly installed behind the first hydraulic gripper and slidably installed behind the second hydraulic gripper. The height-limiting screw is fixedly installed inside the first stop and inside the first hydraulic gripper. The right-angle valve is clamped inside both the first and second hydraulic grippers.

[0006] The first hydraulic gripper includes a support base, a corresponding slot, a second upper stop and a second lower stop, and the corresponding slot is opened inside the support base; the second upper stop and the second lower stop are fixedly installed in front of the support base, and a first stop is fixedly installed in front of the support base.

[0007] The internal structure of the first hydraulic gripper is exactly the same as that of the second hydraulic gripper, and they are mirror images of each other; the first hydraulic gripper is fixed to the first stop, while the second hydraulic gripper is not fixed to the first stop.

[0008] The first hydraulic gripper and the second hydraulic gripper can move away from or towards each other by pushing the drive support structure, and the first hydraulic gripper and the second hydraulic gripper can rotate by rotating the drive support structure. The first hydraulic gripper and the second hydraulic gripper can rotate themselves so that the two front sides of the right angle valve face the processing equipment. The two front sides are processed in sequence in one clamping. The shape of the corresponding slot matches the right angle valve, and the right angle valve is fixed in place by the cooperation of the second upper block and the second lower block with the first block.

[0009] The first stop is made of a stainless steel metal block, and the inside of the first stop has a groove for placing the right-angle valve. Together with the second stop and the first stop, the right-angle valve can only be inserted through a specific direction and angle.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The first hydraulic gripper of this utility model, through its mirror-symmetrical structure with the second hydraulic gripper, synchronously opens and closes to clamp the workpiece under the control of the drive support structure. The first stop and height-limiting screw are fixed to the first hydraulic gripper, forming a precise positioning structure to ensure the unique and correct clamping position of the right-angle valve. During processing, the first and second hydraulic grippers rotate 90° as a whole under the drive support structure, achieving double-sided processing in a single clamping operation. Its rigid structure and precise positioning ensure the efficiency and accuracy of mass production.

[0012] 2. The first stop block of this utility model, through its fixed installation behind the first hydraulic gripper, works in conjunction with the height-limiting screw to provide a precise axial positioning reference for the right-angle valve. Simultaneously, its special contour, in conjunction with the stop block, forms a foolproof structure, ensuring that the workpiece can only be clamped in one correct orientation. This stop block not only provides precise guidance for the sliding movement of the second hydraulic gripper, ensuring the coaxial stability of the dual-jaw movement, but also effectively suppresses processing vibration through its rigid structure. Its integrated design simplifies the overall structure while achieving rapid and precise positioning, ensuring that the workpiece repeatability is stably controlled within ±0.02mm, fully meeting the stringent requirements of high-volume, high-efficiency production.

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] As attached Figure 1 To be continued Figure 3 As shown.

[0020] This utility model provides a machining fixture for a ZM-25 right-angle valve, comprising a first hydraulic gripper 1, a second hydraulic gripper 2, a drive support structure 3, a first stop block 4, a height limiting screw 5, and a right-angle valve 6. The drive support structure 3 is fixedly installed on the outer sides of both the first hydraulic gripper 1 and the second hydraulic gripper 2. The first stop block 4 is fixedly installed behind the first hydraulic gripper 1 and slidably installed behind the second hydraulic gripper 2. The height limiting screw 5 is fixedly installed inside the first stop block 4 and inside the first hydraulic gripper 1. The right-angle valve 6 is clamped inside the first hydraulic gripper 1 and the second hydraulic gripper 2.

[0021] The first hydraulic gripper 1 includes a support base 11, a corresponding slot 12, a second upper stop 13 and a second lower stop 14, and the corresponding slot 12 is opened inside the support base 11; the second upper stop 13 and the second lower stop 14 are fixedly installed in front of the support base 11, and a first stop 4 is fixedly installed behind the support base 11.

[0022] The internal structure of the first hydraulic gripper 1 is completely identical to that of the second hydraulic gripper 2, and they are mirror images of each other; the first hydraulic gripper 1 is fixed to the first stop 4, while the second hydraulic gripper 2 is not fixed to the first stop 4.

[0023] The first hydraulic gripper 1 and the second hydraulic gripper 2 can move away from or towards each other by being pushed by the drive support structure 3, and the first hydraulic gripper 1 and the second hydraulic gripper 2 can rotate by being rotated by the drive support structure 3. The first hydraulic gripper 1 and the second hydraulic gripper 2 can rotate themselves so that the two sides of the right angle valve 6 face the processing equipment, and the two sides are processed in sequence in one clamping. The shape of the corresponding groove 12 matches the right angle valve 6, and the right angle valve 6 is fixed by the cooperation of the second upper stop block 13 and the second lower stop block 14 with the first stop block 4.

[0024] The first stop 4 is made of a stainless steel metal block, and the inside of the first stop 4 is provided with a groove for placing the right angle valve 6. Together with the second lower stop 14 and the first stop 4, the right angle valve 6 can only be inserted through a specific direction and angle.

[0025] This fixture employs a hydraulic-mechanical composite positioning system, achieving precise workpiece clamping through the coordinated action of the first hydraulic gripper 1 and the second hydraulic gripper 2. When the right-angle valve 6 is installed, its reference surface automatically aligns with the height-limiting screw 5, while the contours of the first stop block 4 and the second upper stop block 1314 complete angular positioning, forming a three-dimensional spatial constraint. The drive support structure 3 controls the synchronous closing of the two grippers, ensuring that the workpiece receives a balanced clamping force within the corresponding slot 12 of the support base 11, guaranteeing a positioning accuracy of ±0.02mm.

[0026] During machining, the drive support structure 3 rotates the clamping unit 90°, enabling machining of both sides in a single clamping operation. The integrated foolproof design effectively prevents misoperation, and the rigid structure suppresses cutting vibration. The standardized six-step operation cycle—clamping, positioning, clamping, machining, rotation, and part removal—improves single-piece machining efficiency by 40% and achieves a yield rate exceeding 99.5%, perfectly suited for mass production needs.

[0027] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
